Directions: These questions consist of two statements, each printed as Assertion and Reason. While answering these questions, you are required to choose any one of the following four responses.
Assertion : In the process of photoelectric emission, all emitted electrons do not have the same kinetic energy.
Reason : If radiation falling on a photosensitive surface of a metal consists of different wavelengths then energy acquired by electrons absorbing photons of different wavelengths shall be different.
- a)If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
- b)If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
- c)If the Assertion is correct but Reason is incorrect.
- d)If both the Assertion and Reason are incorrect.
Correct answer is option 'B'. Can you explain this answer?

Explanation:
Assertion: In the process of photoelectric emission, all emitted electrons do not have the same kinetic energy.
Reason: If radiation falling on a photosensitive surface of a metal consists of different wavelengths then the energy acquired by electrons absorbing photons of different wavelengths shall be different.
Explanation:
The photoelectric effect is the phenomenon where electrons are emitted from a material's surface when it is exposed to light or other electromagnetic radiation. The energy of the emitted electrons, known as kinetic energy, depends on the frequency or wavelength of the incident radiation.
1. Assertion is correct: In the process of photoelectric emission, all emitted electrons do not have the same kinetic energy. This is because the kinetic energy of the emitted electrons is determined by the energy of the photons that are absorbed by the material's surface. Different photons have different energies depending on their wavelengths or frequencies. Hence, the kinetic energy of the emitted electrons will vary for different wavelengths of incident radiation.
2. Reason is correct: If radiation falling on a photosensitive surface of a metal consists of different wavelengths, then the energy acquired by electrons absorbing photons of different wavelengths shall be different. The energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. Therefore, photons with higher frequencies (shorter wavelengths) have more energy, while photons with lower frequencies (longer wavelengths) have less energy. When electrons absorb photons of different wavelengths, they acquire different amounts of energy depending on the energy of the photons. This difference in energy acquired by electrons leads to different kinetic energies of the emitted electrons.
Explanation of the relationship between the Assertion and Reason:
The Reason correctly explains why the Assertion is true. The assertion states that all emitted electrons do not have the same kinetic energy, and the reason explains that this is because the energy acquired by electrons absorbing photons of different wavelengths is different. The energy of photons is directly related to their wavelength or frequency, and this difference in energy results in different kinetic energies of the emitted electrons.
Conclusion:
Both the Assertion and Reason are correct, and the Reason is a correct explanation of the Assertion. Hence, the correct answer is option 'B'.
